TI-Nspire Lua Scripting Tutorials

Texas Instruments TI-Nspire Scripting Support Page


Lua Scripting Quick Start

As part of European Coding Week (October 2015), these three video tutorials touch briefly on key aspects of Lua Scripting for TI-Nspire, from beginner, through intermediate to advanced topics. Follow along, pausing the videos frequently to try out the ideas shown, and then work carefully through the tutorials that follow to make sure you cover all that you need to know to create powerful documents for teaching and learning using Lua and TI-Nspire.

Introduction to Lua Scripting: Video 1 (57 minutes): Painting text and simple graphics to the screen, controlling movement of screen objects.

Introduction to Lua Scripting: Video 2 (59 minutes): Linking to TI-Nspire variables, and building documents by inserting pre-made screen objects (buttons, sliders, controls...)

Introduction to Lua Scripting: Video 3 (56 minutes): Using the timer to create animations, working with images, and simple BlueTooth controls.

If you would like a taste of Lua without leaving your browser, feel free to visit and explore the Lua JavaScript page. This offers a sampler of documents that you can try by clicking the "run your code" button. You can even try out your own code using the OnLine Lua Script Editor. This work, based on the great efforts of Jim Bauwens from Belgium, is still very much a work in progress... but it does work (mostly) on iOS (iPads and iPhones) and Android tablets, as well as the more usual platforms!

You may also wish to do some Lua scripting on your TI-Nspire handheld. In addition to the excellent Oclua (On-Calculator LUA), developed by Olivier Armand, we now have another option that promises great things: TIDE (TI-Integrated Development Environment), currently in development by Nadrieril Feneanar . This offers a scripting page and a Lua page, which automatically picks up the script as you write it. Many of the tutorials that follow support these options.

And where to from here? Once you finish these lessons and want to go further, head across to the wonderful Nspired Lua website for their tutorials, documentation and wiki.
